The pH reading and/or temperature reading doesn’t show

The readings are out of range. The pH range of the meter is from 3,5 to 9,0 and the temperature range is from -9 C to +50 C. Verify if the “pH/Temp.” switch on the back of the unit is in the right position.

The results of various measurements are very different or seem to be unreliable

Did you take off the protection cap of the probe? Did you take enough readings to confirm your findings?Did you clean the probe properly and did you remove the oxidation?Did you water the soil before testing if the soil is (too) dry?Did you measure in plain soil without any obstacles (roots etc..)?Did you keep enough distance from the side and the bottom of the pot?Did you measure in the same type of soil doing several measurements?Is there fertilizer near the probe or is there a fertilizer stick in the pot?Did you damage the probe by using too much force?
